WAGON-WHEEL H'U B.

SPECIFICATION forming part of Letters Patent No. 587,841, dated August 10, 1897'. Application med rune 7,1397. serial No. 639,714. cromada.)

To all whom, t muy concern,.-

Be it known that I, JAMES D. MATTISON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented vcert-ain new and useful Improvements in Wagon-Vheel Hu bs and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art toA which it appertains to make and use the same.

My invention relates to improvements in hubs for wagon and other wheels; and its novelty and many advantages will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure l is a diametrical sectional View of my improved hub in position upon an axlespindle. Fig. 2 is a perspective sectional view of the annular oil-receptacle, and Fig. 3 is a similar view of the cap.

Referring by letter to the said drawings, A indicates an axle having a spindle a with the usual collar b at its inner end and the threads c at its outer end, and B indicates the body of my improved hub, which is formed in one piece of steel or other suitable met-al. This body B is provided with the usual radially-disposed spoke-sockets d, and it has the interior threads e f at its inner and outer ends and also has its interior reduced in di- -ameter at its middle, so asto afford the interior bearing-surface g, which is designed to serve the purpose of a housing, the proportion being much larger than illustrated. The said bearing-surface or housing g is provided at its middle with the groove h, and in said groove is arranged a ring t', which may be split, if desired, and is designed to serve a purpose presently described.

A indicates an eXteriorly-threaded ring, which is arranged in the threaded end f of the hub-body B and loosely surrounds the axle-spindle and is provided with the inwardly-directed annular flange a'. B' indicates an annular oil-receptacle, which is exteriorly threaded to engage the threaded end e of the body B and is provided with the inwardly-extending annular flange b', and C indicates main bearing-rollers, which have peripheral grooves j at their middle receiving the ring z', whereby they are held against ameter for the greater part of their length,and

they are provided adjacent to their endswith the enlarged portions m, which bear againstV the reduced portions It of the rollers C, and are further provided with the end portions n, which bear against the flanges a b of the ring A and'oil-receptacle B', and with the grooves p to receive the inwardly-extending flanges q of the movable or revoluble rings E and the reduced portions r, which bear against the inner sides of the rings, as illustrated. The said rings E serve to hold the intermediate rollers D in their proper relative positions, and through the medium of said rollers D said rings E also serve to hold the main bearing-rollers O in their proper relative positions. It will be further seen that while the bosses Z of the rollers C do not in operation engage the rings E or the flanges o b', yet they extend to points between the rings and the anges a b' and consequently are enabled to serve the important function of preventing the rollers C from dropping out of place when the hub is removed from the axle-spindle.

The annular oil-receptacle B is provided with a flange s, which snugly receives the collar b of the axle-spindle, so as to assist in eX- cluding dust, and it also has the annular oilchamber t, into which lubricant is introduced in a manner presently described. In this oilchamber t is arranged a washer F of phosphorbronze or other suitable material which snugly fits the axle-spindle and is interposed between the collar l) andthe inner. wall of the receptacle B', as shown. The bearing between this washer F of phosphor-bronze and the collar b is lubricated, and in consequence the friction between the hub and the spindle incident to end thrust is reduced to a minimum.

G indicates a nut which is mounted on the threaded end c of the axle-spindle and serves to hold the hub thereon. H indicates a washer of phosphor-bronze or other suit-able material interposed between the nut G and ring A', and I indicates a cap which is eXteriorly threaded to engage the threaded end f of the hub-body B and serves to close the outer end of the hub, so as to assist in eX- cludin g dust from the interior thereof. This cap I has the interior annular recess J adjacentto its inner edge, as shown, which recess holds the lubricant and applies the same to the contiguous surfaces of the washer H, ring A', and nut G, so as to assist in reducing the friction incident to end thrust to a minimum. The cap I further serves to prevent lubricant from working out between the cap I and the body and consequ ently obviates the collection of oil on the outside of the hub, and by keeping the exterior of the hub dry reduces the collection of dust thereon to a minimum, which is an important advantage.

Lubricant is introduced to the oil-receptacle B and cap I through apertures a7, normally closed by screws CL2-and it is applied to the washers F H and the parts against which they bear only and does not rind its way to the roller-bearing, such bearing requiring no lubrication, which is an important advantage.

I prefer to form the washers F H of phosphor-bronze, but do not desire to be understood as connin g myself to the same, as they may in some cases be formed of other hard metal.

It will be observed from the foregoing that my improved hub may be made of the same size and shape as the hubs of ordinary wagonwheels and may as quickly and easily be secured upon and removed from an axle-spindle. It will also be observed that by reason of the construction of the hub and the manner in which the end bearing parts are lubricated the friction incident to the turning of the wheel will be reduced to a minimum.

Having thus described my invention, what I claim isl. The hub described, comprising the body having the interior threads at its opposite ends and the interior bearing-surface at an intermediate point of its length, the annular, threaded oil-receptacle arranged in the inner end of the body and having the annular oilchamber and also having the inwardly-directed annular liange, the hard-metal Washer arranged in the oil-chamber of the oil-receptacle, the threaded ring arranged in the outer end of the body and having the inwardly-dithe latter engaging the reduced portions adrected annular flange, the ring arranged in a groove in the interior bearing-surface of the body, main bearing-rollers having peripheral grooves receiving said ring and also having the reduced portions adjacent to their ends and the bosses at their ends, rollers arranged intermediate of the main bearing-rollers and having the reduced intermediate portions and the enlarged portions adjacent to their ends,

jacent to the ends of the main bearing-rollers, and also having end portions bearing on the inwardly-directed flanges of the oil-receptacle and the ring, movable rings surrounding and engaging theintermediate rollers and also surrounding the bosses of the main bearingrollers, and the threaded cap arranged in the outer end of the body and having the in,- terior recess or channel for the reception of oil, substantially as speciiied.

2. The hub described, comprising the body having the interior threads at its inner end, the annular threaded oil-receptacle arranged in the inner end of the body and having the annular oil-chamber, the hard-metal Washer arranged in the oil-chamber of the oil-receptacle, and antifrictionfrollers carried by the body and adapted to bear on an axle-spindle, substantially as specified.

3. The combination of an axle-spindle havf ing a collar at its inner end and threads at its outerend, and a hub comprising a body having the interior threads at its ends, the Vannular, threaded oil-receptacle arranged inthe inner end of the body and receiving the collarof the spindle and having the annular oil-chamber and the inwardly-directed annular flange, the threaded ring arranged in the outer end of the body and having the inwardly-directed annular ange, main bearing-rollers interposed between the body and the axle-spindle, intermediate rollers interposed between the main bearing rollers and bearing on the iianges of the oil-receptacle and ring, the threaded cap arranged in the outer `end 1L-105 the body and having the oil-receiving channel, the nutarranged Within said cap and mounted on the threaded end of the spindle, the hard-metal Washer interposed between the collar on the axle-spindle and the inner Wall of the oil-receptacle, and the hard-metal Washer interposed between the nut and the threaded ring., substantially as specified.

In testimony whereof I aiix my signature in presence of two Witnesses.

JAMES D. MATTISON.
